  1. Pry the boots off either end of the cylinder and remove the pushrods. Push in on one of the pistons to force out the other piston, its cup, the spring, and the piston itself.
  2.  
  3. Wash the pistons, the wheel cylinder housing, and the spring in fresh brake fluid. Dry them with compressed air.
  4.  
  5. Inspect the cylinder bore wall for signs of wear. If it is badly scored or pitted, the entire cylinder should be replaced. Light scratches or corrosion can be removed with crocus cloth or a hone.
  6.  

To assemble:
  1. Dip the pistons and new cups in clean brake fluid. Coat the cylinder wall with brake fluid.
  2.  
  3. Place the spring in the cylinder bore. Position the cups in either end of the cylinder with open end of the cups facing inward (toward each other).
  4.  
  5. Place the pistons in either end of the cylinder bore with the recessed ends facing outward. Slide the pistons into the bore until the ends are flush with the end of the bore. Open the bleeder to relieve any pressure.
  6.  
  7. Fit the boots over the ends of the cylinder and push down until each boot is seated.
